- Which of the following represents the void ratio of soil sample whose porosity is 0.452?

The moisture content in a soil sample is 18.2% and specific gravity of the soil particles is given by 2.65. What is the void ratio for sample, if the soil is fully
saturated?

If the degree of saturation of soil is given by 67.89%, what is the percentage of air content of the soil?

Which of the following expression represent the relative compaction of soil, where variables have their standard meanings?

The type of fluid in which flow and fluid properties does not change with time at any given location, is known as______

Fora flow, the velocity components are given by u =$$(\lambda xy^{2}-x^{3}y^{2})$$ and v=$$(x^{2}Y^{3}-3y^{3})$$.what is the value of $$\lambda $$ for the possible flow field which includes steady in compressible flow?

What is the value of angle (degree) between stream lines and equipotential lines at the point of intersection in the flow net?

What is the cross-sectional area (sq. m) of the channel, if its hydraulic radius and wetted perimeter is given as 300 cm and 860 cm respectively?

The flow in a channel is laminar and Reynolds number is given by 1200. What is the friction factor for the channel?

A circular pipe of diameter 0.5 m carries the discharge of 50 liters/s. The head loss due to friction in pipe is 0.15 m and friction factor for the pipe is given as 0.01.
What is the length (m) of pipe?
